tltti i ti'; S 51 AUTOMOBILE VENTILATOR.

Application filed June 28,

The present invention relates to improvements in ventilators, and has reference more particularly to a ventilator construction primarily for use in conjunction with the top of limousines, sedans, coupes or other types of closed automobiles.

One of the important objects of the present invention is to provide a ventilator of the above mentioned character which may be readily and easily adjusted to secure thedesired amount of circulation of air in the closed automobile.

A further object of the invention is to provide a ventilator of the above mentioned character, which is simple in construction, inexpensive, strong and durable, and further well adapted for the purposes for wh ch it is designed.

Other objects and advantages of this invention will become apparent from the following description.

In the accompanying drawing forming a part of this specification, and in which like numerals designate like parts throughout thesame:

Figure 1 is a bottom plan view of the ventilator constructed in accordance with the present invention, the same being shown arranged in the ceiling or top of a closed vehicle.

Figure 2 is a detail vertical sectional view thereof, parts being shown in side elevation.

Figure 3 is a detail view of the connection between the hinged lid and the actuating rod, and

Figure 4 is a detail sectional view of thespider and the adjacent portion of the actuating rod.

In the drawings, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 5 designates the crown wall or ceiling of a closed body automobile, the same being formed at a desirable point with a rectangular shaped opening 6.

Rigidly disposed within this opening is my improved ventilator, the same coinprising a substantially rectangular shaped metallic frame or shell 7. This frame is open at its top and bottom, and is formed intermediate the top and bottom thereof with the spaced horizontal spiders 8, the central webs 9 of which are formed with registering openings 10, through which is slidable a vertical rod 11.

Hingedly secured at 12 to the forward 1928. Serial No. 119,110.

edge of the frame or shell 7 is a closure lid 13 for the open top of the frame. The hinged connection includes axial coil springs 13' that normally act to maintain the lid in a closed position with respect to the frame. As is clearly shown in Figure 2, the upper edge portion of the frame or shell 7 extends above the top surface, of the ceiling 5 and a depending flange 14 is associated with the closure lid for engagement with the upper edge portion of the frame or shell. A laterally extending flange 15 is formed on the lower edges of the frame for engagen'ient With the bottom face of the ceiling in the manner as clearly shown at 15 in Figures l and 2.

The upper end of the rod 11 is bifurcated as illustrated at 16, with reference more particularly to Figure 3. A pair of spaced ears 1T depend from the intermediate portion of the bottom of the closure lid 13. A connecting link 18 is pivotally secured at its up per end between the spaced cars 17 as at 19, the lower end of said link being pivotally supported in the bifurcated upper end 16 of the vertical rod 11 as at 20. In this manner, an operative connection between the upper end of the vertical rod and the closure lid 13 is provided, and the purpose thereof will be hereinafter more fully described.

A cross bar 21 extends transversely across the bottom portion of the frame or shell 7, and the same is provided with an opening 22 in the central thickened portion 23 thereof. A rod 24 extends through this opening 22, the upper portion of the rod being threaded as illustrated at 25 for cooperation with the threaded socket 26 provided in the lower end of the vertical rod 11, which rod 11 is of a greater diameter than the rod 24.

A knurled hand wheel 27 is provided on the lower end of the rod 24 to facilitate the actuation of said rod and for the purpose of providing the vertical movement of the rod 24, I provide the intermediate portion of the rod with the spaced stop collars 28 and 29, respectively. The collar 28 is adapted to engage the upper face of the thickened portion 23 of the cross bar 21, while the collar 29 engages the bottom face of the central thickened portion 23 in the manner as clearly shown in Figure 4. These stop collars may be secured on the rod 24 in any suitable manner.

It is obvious that when the thumb wheel 27 is turned in one direction, the rod 24 will be rotated causing the threaded upper end to cooperate with the threaded socket 26 provided in the lower end of therod 11 in a s g the rod upwardly and simultaneously raising the lid 13 to an open position so that the desired circulation of air through the opening 6 in the ceiling of the car may be obtained. Manifestly by turning the rod 24 in the reverse direction, the rod 11 will be lowered, thus moving the closure lid 13 to a closed position and the actual coil springs 13 will cooperate in maintaining the lid in its closed position.

The purpose of the link 18 is to provide a means whereby the rod 1.1 will move vertically, upwardly and downwardly and per mit the positive swinging movement of the closure 11d, 13., Arranged within the frame 7 is a moisture collecting trough or gutter 3,0 and associated with t re same is the discharge ipe 3,1.

It will thus be seen from the foregoing description, that I have provided a highly novel yet simple and eflici'ent ventilator for closed types of autQmobiles, which may be readily and easily installed without necessitating any material alterations and the simplicity of my improved ventilator enables the 'same' to be readily and easily actuated.

While I have shown the preferred embodiment of my invention, it is to be under stood that various changes in the size, Shape and arrangement of parts may be resorted a rod adapted for vertical slidable movement through said openings, a link afiording the pivotal connection between the upper end of the rod and the intermediate portion of the bottom of said lid, means whereby the rod may be raised or lowered for actuating the lid, said means comprising a threaded rod, the lower end of the first mentioned rod having a threaded socket formed therein for cooperation with the upper threaded end of the last mentioned rod, :1

cross bar through which the threaded rod' extends, a handle supported on the lower end of the threaded rod for actuating the same, and stop collars secured on the threaded rod and arranged on opposite sides of the cross bar for preventing the vertical movement of said threaded rod.

In testimony whereof I affix my signature.

GEORGE A. BURKHOLDER.
